1. Connections and Cables

6. CONNECTIONS AND CABLES

6.1 Inputs

The LX-308B stereo inputs use two 20K

balanced 1/4" phone jacks per channel, with (+) signal

on the tip, the (-) signal on the ring, and ground on the

sleeve. If you wish to drive a mono source into the stereo

mix, simply plug your signal into the right channel input.

Channels 1 and 2 are switchable to add 30dB gain for low

impedance dynamic microphones.

6.2 Sub Inputs

The Sub inputs are nominal 10K

types on 1/4" phone jacks. They feed directly to the mix

busses at a nominal +4dBu level and are useful for cou-

pling multiple mixers

6.3 Sub Outputs

The Sub Outputs are unbalanced types on 1/4"

phone jacks. Typically, they will feed sub inputs on ad-

ditional mixers. Nominal operating level is +4 dBu.

jacks, which means they have balanced impedance with a

single-ended signal source and can be wired balanced or

unbalanced. Nominal operating level is +4 dBu and maxi-

mum headroom is +22dBu.

phones and mixer line outputs), or if either of these lines

and speaker cables are run parallel for long distances,

crosstalk may be significant. In fact, the crosstalk (sig-

unbalanced

nal leakage between cables) can cause an electronic feed-

back loop, oscillation, and possibly damage to the

equipment. To minimize crosstalk, physically separate

low level (microphone) cables from speaker cables by the

greatest feasible distance. At any point where cables meet,

run low level cables perpendicular to high level or speaker

cables. If low and high level or speaker cables must be

run parallel and in close proximity to one another, they

should be bundled separately.
